Improved understanding of threatened species diversity is important for long-term conservation planning and natural area management, especially under ongoing global change. Geodiversity - the diversity of earth surface materials, forms and processes - may be a useful biodiversity surrogate for conservation planning, as well as having conservation v...
Context‘Conserving Nature’s stage’ has been advanced as an important conservation principle because of known links between biodiversity and abiotic environmental diversity, especially in sensitive high-latitude environments and at the landscape scale. However these links have not been examined across gradients of human impact on the landscape. Obje...
Aim: Geodiversity underpins biodiversity, but the contribution of specific geofeatures or landforms has rarely been explored. In this study, we use multiple vascular plant species diversity measures on alpha, beta and gamma levels to explore the linkage between biodiversity and co-located landforms (e.g. gullies, dunes and lake shores). We hypothes...

The capability of present conservation actions to protect and sustain biodiversity in the face of global change is under debate. One solution could be Conserving Nature´s Stage framework which states that geodiversity (e.g. data on geological, geomorphological and hydrological richness) c...
Mapping of ecosystem services (ESs) provide valuable information on the geographical variation of ESs and their relation to overall diversity. Although the relationship between biodiversity and ESs has been intensively explored, little is known how geodiversity (i.e., variety of geological, geomorphological and soil features) is associated with dif...
Our existence on Earth is founded on a vital nature, which supports human physical and mental health. However, nature is often depicted only through biodiversity, whereas geodiversity-the diversity of non-living nature-has so far been neglected. Geodiversity consists of assemblages, structures, and systems of geological, geomorphological, soil, and...
Article Impact statement: Conservationists could better acknowledge geodiversity by following the steps of promotion, collaboration, integration, and implementation. This article is protected by copyright. All rights reserved
The non-living and the living nature are inherently connected. Geodiversity, that consist of the variation in geology, soils, topography, geomorphology and hydrology, is seen as the foundation and stage for biodiversity. Underlying theory suggests that the increasing variation in the abiotic foundation creates and maintains available niche space fo...
Geodiversity is an emerging, multi-faceted concept in Earth and environmental sciences. Knowledge on geo-diversity is crucial for understanding functions of natural systems and in guiding sustainable development. Despite the critical nature of geodiversity information, data acquisition and analytical methods have lagged behind the conceptual develo...
1. Current global environmental change calls for comprehensive and complementing approaches for biodiversity conservation. According to recent research, consideration of the diversity of Earth's abiotic features (i.e., geodiversity) could provide new insights and applications into the investigation and management of biodiversity. However, methods t...
The diversity of nature consists of two complementary components: biological diversity (biodiversity) and abiotic diversity (geodiversity). Biodiversity is widely acknowledged in both research, and conservation and management practices, whereas geodiversity (the variety of abiotic features and processes of the land surface and subsurface) is just e...

Aim: Conserving freshwater biodiversity in a rapidly changing world requires updated planning schemes and research efforts. Geodiversity – the diversity of Earth surface forms, materials and processes – and biodiversity are interlinked at a fundamental level. This relationship is being considered in a growing number of studies, yet research from fr...
Context
One approach to maintain the resilience of biotic communities is to protect the variability of abiotic characteristics of Earth’s surface, i.e. geodiversity. In terrestrial environments, the relationship between geodiversity and biodiversity is well recognized. In streams, the abiotic properties of upstream catchments influence stream commu...
Geographical information systems (GIS)-based approaches support the traditional empirical assessment and monitoring measures to indicate large-scale environmental alterations caused by global change. We examined the relationship between cover patterns of emergent aquatic plants derived from the CORINE land cover database, and environmental gradient...
In physical geography, the focus of research is on the natural processes of the Earth which provide the physical settings for human activities. Technical innovations like geographical information system (GIS) and remote sensing combined with statistical analysis have become effective approaches to study complex spatial patterns at various scales. M...

Geodiversity describes the abiotic diversity of the earth's surface (e.g., soil, landform and bedrock types, hydrology, and elevation) and
can be used as a surrogate for biodiversity. Alternative and complementing approaches to quantify biodiversity are badly needed due to harmful effects of global change. In this project, we study if geodiversity has any influence on the temporal changes in biological
communities, whether geodiversity-biodiversity relationships are similar across different places and whether high geodiversity areas
support high biodiversity. The project has both research-focussed and practical applied benefits, emphasising the novelty and boldness
of our multidiciplinary research exercise.
